Summary of Recommendations

DIAGNOSIS

When examining a patient with suspected carpal tunnel syndrome (CTS), clinicians should use Semmes-Weinstein monofilament testing (SWMT), using the 2.83 or 3.22 monofilament as the threshold for normal light touch sensation and static 2-point discrimination on the middle finger to aid in determining the extent of nerve damage. In those with suspected moderate to severe CTS, clinicians should assess any radial finger using the 3.22 filament as the threshold for normal. Semmes-Weinstein monofilament testing should be repeated by the same provider. (A)
